Please note the domed roof. They're also called wickiup, wetu (that's the Wampanoaq term) or wiigiiwaam (which is how you write it in the Ojibwe language). 

People tend to say wigwam in the North East of the USA and wickiup in the South West. 

People used to live in wigwams full-time, though nowadays they're only really used for ceremonial purposes and by people who like being solitary.

A wigwam is perhaps eight feet across, made with a frame of saplings lashed together. A wigwam will usually have a central hole for smoke to escape, and is covered with leaves or mats or hides. A wigwam might have grass beds inside, and are said to be snug even in snowy weather (though I find this hard to believe).

Best of all, when a wigwam gets a bit old and grubby and past repair, you can burn it and erect a new one in the same place, using the same holes to hold the poles steady, in about three days.

Obviously this system entirely does away with the concept of Spring Cleaning, which can only be A Good Thing.

(While I'm here: a tepee, strictly speaking, has straight sides and is more temporary, and possibly even portable; but the word wigwam is quite often used for both types of dwelling.)

Although wigwams aren't lived in, much, anymore, similar buildings called aqal are used by nomadic Somali people. In Britain, wigwams are sometimes constructed by New Age travellers. These tend to be covered in plastic tarpaulins, and called bender huts.
